KNUTE S. ASLAND, OF CHICAGO, ILLINOIS.

MUSIC-LEAF TIIRNER AND HOLDER.

To all whom it may concern Be it known that I. KNUTE S. AsLANn, asubject of the King of Norway, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Music-Leaf Turners and Holders, of which the followingis a specification.

This invention relates to improvements in a device to be used forholding and turning the leaves of sheet music, and while it is moreespecially intended to be used in connection with pianos and organs, forholding and turning sheets of music, while the same is being played 011such instruments, yet it is applicable for use by members of orchestrasand other musicians, and in such instances can be supported on the musicracks or stands ordinarily used by them, and it consists in certainpeculiarities of the construction, novel arrangement, and operation ofthe various parts thereof, as will be hereinafter more fully set forthand specifically claimed The principal object of the invention is toprovide a music leaf turner and holder which shall be simple andinexpensive in construction, strong, durable, and efiicient inoperation, and so made that it can be mounted on a suitable support suchas a piano, or organ, or music rack, and'can be operated by a pedal orlever which may be pressed by the foot or the knee of the musiclan.

Another object of the invention is to provide means whereby the sheetsof music may be separately turned on the holder from one side of themusic support to the other.

Still another object is to so construct the device that the arm andfingers of the apparatus employed for engaging and turning the sheetwill be automatically moved to its initial position and engage thesheets one at a time automatically, thus requiring pressure or power tooperate the turning or throwing arm in one direction only.

Various other objects and advantages of the invention will be disclosedin the subjoined description and explanation.

In order to enable others skilled in the art to which the inventionpertains, to make and use the same I will now proceed to describe itreferring to the accompanying drawing in which Figure 1, is a front viewin elevation of a music leaf holder and turner embodying Specificationof Letters Patent.

Like numerals of reference refer to corresponding parts throughout thedifferent views of the drawings.

The base of the device is designated as a whole by the reference numeral30, and is made of metal and preferably elongated in form as shown inFigs. 1, and 5, of the drawings, so that it may be placed longitudinallyon a piano frame ust above the keyboard thereof or may be mounted on amusic stand or rack and secured in position thereon if desired. The base30, is provided with a cavity 31, in its lower surface for the receptionand operation of certain parts of the mechanism as will be presentlyexplained. As is shown in Figs. 13 and 14, the base 30, is provided nearits central portion with an enlargement 32, which extends into thecavity 31, and said enlargement is formed with a ci cular cavity 33,-for the reception and operation of a pinion or gear 34, which is fixedto a shaft 35, which is extended vertically through the upper portion ofthe base 30, and is journaled at its lower end in a suitable opening ina plate 36, which is secured to the lower surface of the enlargement 32,of the base. Located within the cavity 31, of the base and between therear wall of the latter and the enlargement 32, is a rack 37, whichengages the pinion or gear 34, and has at one of its ends an arm 38,which extends forwardly of the base and has connected to its free end aspring 39, which spring is secured at its other end to the base and isemployed to retract the rack. Loosely connected to the arm 38, near itsconnection with the spring 39, is a rod or connection 40, which isextended through a suitable opening in one end of the base and may haveconnected thereto a cord or connection 41, to pass over a pulley 42,(see Fig. 1, of the drawings) which pulley may be mounted on the supportfor the device. The cord or connection 41, may be attached to apedal orlever (not shown) which can be operated by means of the foot or knee ofthe musician.

of which is extended the shaft 35, which shaft has loosely mountedthereon at one of its ends the turning or throwing arm for the musicsheets which arm is designated as a whole by the reference numeral 44,and

is provided with a longitudinally extended groove 45, (see Fig. 16,) forthe reception and operation of a plunger 46, (see Fig. 19) which carriesat its end adjacent to the head 44 of the throwing arm a cam bracket 47,which is provided on its upper surface with a pin 48, and which bracketlies on the upper surface of the arm 44, when the plunger 46, is inplace within the groove 45, of said arm. As shown in Fig. 16, the arm44, is provided at its end opposite the head 44 with a plate 49, towhich another plate 50, having a head 51, on its inner surface at itsouter end is secured, the other end of the plate 50, being secured to arecessed block 52, which is located at the outer or free end of thegroove 45, and between the plates 49, and 50, so that its recess willstride the reduced portion of the plunger 46, which plunger is providedat its end opposite that on which the cam bracket 47, is mounted, with aflat extension 53, which is provided on opposite sides with pins 54, and55, to engage the cam slots of the music sheet engaging fingers 56, and57, respectively. The finger 56, is pivotally mounted on a pin 58, onthe inner surface of the plate 49, of the throwing arm, and the finger57, is similarly mounted on a pin 59, on the inner surface of the plate50, of said arm, and as the fiat extension 53, of the plunger extendsbetween said fingers, it will be understood that the pin 54, on theextension 53, will fit in the cam slot 60, of the finger 56, while thepin 55, on the extension 53, will fit in the cam slot 61, of the finger57. The reduced portion of the plunger 46, has located therearound acoiled spring 62, which rests at one of its ends against the cam bracket47, and at its other end against the recessed block 52, said springbeing located in the groove 45, of the turning arm. As the cam slots 60and 61, of the fingers 56, and 57, respectively, are located one belowthe bearing point and the other above the bearing point of said fingersit is apparent that as the plunger 46, is reciprocated, these fingers,will. have alternate movement so that they will project one at a timeabove the upper surface of the throwing or turning arm, to the end that,one of said fingers, to-wit, 56, will act to retard or hold the sheet infront thereof, while the other finger 57, will engage its rear surfaceand continue in contact with said surface during the operation ofturningthe sheet.

Fixed to the shaft 35, above the head 44 of the throwing arm is a collar63, which is provided with a cut out portion or recess 64, which recesscommunicates with the opening in said collar which receives the upperportion of the shaft 35, and is for the reception and operation of awing trigger 65, which has at its inner portion a projection 66,extended into a slot in the upper end of the shaft 35, in which end saidpro jection is pivoted so as to permit of the upward and downwardmovement of the trigger 65, as will be readily understood by referenceto Fig. 26, of the drawings. The collar 63, is provided on each side ofthe recess 64, therein, with downwardly extended projections 67, and 68,which projections are located on opposite sides of the turning arm 44,and will permit the collar 63, to be moved independently ofthe arm 44,until restricted by said projections.

As shown in different views of the draw ings, the raised or enlargedportion 43, on the base 30, is segmental in shape, and has secured toits rear and straight portion an upright 69, which has on its frontsurface near its upper and lower ends forwardly and upwardly extendedprojections or pintles 70 and 74, to engage rings 71 and 76respectively, employed in the upper and lower portions of the musicsheets 72, and the upper and lower portions of the stilfeners 73, forsaid sheets, which stiffeners may be made of metal or other stiffmaterial and placed near the side and lower edges-of each of said sheetsto render them less flexible at said portions so that they may be morereadily supported by the pintles 70, and 74, on the upright support 69,and turned by the turning arm 44, when desired. Secured to the lowerportion of the upright 69, and extended forwardly above the col lar 63,and if desired, so as to rest lightly thereon, is a bracket or cap 75,which carries an upwardly ext-ended pintle 74, to engage a ring 76,passed through the sheets 72, and the stifteners 7 3, therefor, at theiredges adjacent to said pintle. The bracket or cap 75, has on its lowersurface at its perimeter a downturned flange 77, (see Figs. 3, and 14)which flange is cut away as at 78, in its portion adjacent to theinitial position of the turning arm, and is for the purpose of acting asa lock or restriction to engage the pin 48, on the cam bracket 47 ,whichpin engages the inner surface of said flange after the arm 44, has beenturned a certain distance in the operation of turning a sheet, and so asto prevent the outward movement of the plunger 46, and the actuation ofthe fingers 56, and 57, until the turning arm has been returned almostto its initial position. I

From the foregoing and by reference to the drawings, it will be readilyunderstood and clearly seen, that, assuming the parts are in thepositions shown in Figs. 1, 2, 3, and 6, of the drawings, and that thedevice is mounted on the ledge of a piano or organ above the keyboardthereof, or is supported on a music stand or rack, and that connections40, and 41, of the rack 37, are operated by a lever (not shown) and thatthe con nection 41, is passed over a pulley 42, it is obvious that byapplying pressure in the proper direction to said lever, the spring 39,will yield sufficiently to allow the rack 37 to be moved in such a wayas to cause the pinion or gear 34, and the shaft 35, thereon, to beturned in the opposite direction, in which operation it will beunderstood that as the arm 44, is loosely mounted on the shaft 35, andthe collar 63, is fixed on said shaft, that the shaft will be turned aslight distance independently of the turning arm, in which action thewing trigger 65, will be caused to travel from the position shown inFig. 6, and by reason of the bevel of the cam bracket 47 to ride overthe latter as shown in Fig. 7, until the collar 63, and the wing trigger65, reach the positions shown in Fig. 8, when it is apparent that thewing trigger will drop in front of the bracket 47, and the projection68, on the collar 63, will strike the rear portion of the arm 44, thuscausing the arm and collar to rotate with the shaft 35, until the musicleaf is turned from its initial position to the opposite side of thesupport 69, when by releasing the pressure on the lever or means foroperating the connections 40, and 41, of the rack 37 it is manifest thatthe spring 39, will retract the rack 37, in which operation the pinionor gear 34, will be turned in the op posite direction from that of themovement of the rack, which operation will cause the arm 44, to bereturned toward its initial position, the collar 63, and the wingtrigger 65, also being returned in unison with the arm, until the pin48, on the cam bracket 47, has reached the end of the flange 77 on thebracket or cap 75, at which time the curved portion of the wing trigger65, will be caused by the pressure of the spring 39, through theinstrumentality of the rack 37, shaft 35, and pinion 34, to force thebracket 47 and plunger 46, outwardly from the said shaft, thus causingthe rear finger 57 to be depressed and the front finger 56. to be raisedso that the latter will rest against the front surface of the musicsheet and press the same rearwardly when by slight further movement ofthe arm 44, actuated by the spring 39, the wing trigger 65, will bereleased from the cam bracket 47 when the spring 62, will force saidbracket and plunger 46, toward the shaft 35, thus causing the finger 57,to be raised rearwardly of the music sheet so as to engage thestiffeners 73, thereon when by again pressing the lever or operating themeans for actuating the connections 40, and 41, with the rack 87, theabove described operation will be repeated.

An important feature of the invention is the music sheet holder fullyillustrated in Figs. 29 to 32 inclusive, and consists of one or moresheet holding members 7 3, each of which is made of any suitablematerial but preferably of sheet metal, and bent at its lower orhorizontal portion to form a channeled member 79, (see Fig. 31,) for there ception of the lower edge of the music sheet, that is to say, thepiece out of which the member 7 is formed, is bent so as to provide twoparallel portions 80, and 81, which are spaced apart sufiiciently toreceive the lower portion or edge of a sheet of music. Extended upwardlyfrom each of the portions 80, and 81, and at one of their ends areparallel members 82, and 83, respectively, which are provided withopenings 84, to receive the rings 71, and 7 6, which, when the holder isplaced in position on the upright 69, will encircle the pintles 70, and74, thus allowing the stifieners or holders 7 3, to be freely turnedfrom one side of the support to the other. When the piece of musiccomprises more than one sheet, a holding member 73, is used on eachsheet and will embrace the lower adjacent corners as well as theadjacent edges of the sheets and will be loosely connected together bymeans of the rings 71, and 7 6, which as before stated, are passedthrough the openings 84, in the members 82, and 83, as well as throughopenings in the music sheets, thus binding them together in a groupwhich can be supported on the pintles 70, and 74, of the upright so thatthey can be turned thereon one at a time as desired.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is- 1. In a device of the characterdescribed, the combination with a supporting frame including a base andan upright, of means on the upright to pivotally support one or moresheets of music, a sheet turning arm pivoted at one of its ends on saidbase at the lower end of the upright, means engaging said pivot wherebyit and the arm may be turned in one direction, a spring engaging saidmeans to actuate it and said arm in the opposite direction, a pair offingers pivotally supported on the arm to alternately engage a sheet andeach having a cam-slot, a spring-pressed plunger on the arm and extendedbetween said fingers, pins on the plunger engaging the slots of thefingers, a cam-bracket on the plunger, a wing-trigger pivoted forvertical movement on said pivot and adapted to actuate the cam-bracketand plunger in one direction and thereby cause said fingers toautomatically engage a sheet.
